I have checked with Diego and he told me that the main thing it to declare the classes as rdfs:Class and owl:Class instances. In RDF/XML we can use <rdf:type>, for example:

<rdfs:Class rdf:about="....">
    <rdf:type rdf:resource="http://www.w3.org/2002/07/owl#Class"/>
    <!-- ... -->

Which is the abbreviated for:

<rdf:Description rdf:about="...">   
    <rdf:type rdf:resource="http://www.w3.org/2002/07/owl#Class"/>
    <rdf:type rdf:resource="http://www.w3.org/2000/01/rdf-schema#Class"/>

Simmilary, he also suggests to declare the properties as owl:DatatypeProperty or owl:ObjectProperty, apart from rdf:Property.
